HOSE- COUPLING.

SPECIFICATION Application filed May 8, 1903.

detachable type wherein the separate pipe members may be readilyconnected and disconnected with great facility, and thereby obviatingthe objections to the common type of screw-joint for hose-couplings.

To this end the invention contemplates an improved construction ofhose-coupling embodying simple and positive means for se-. curelylocking the separate members of the coupling together, while at the sametime permitting of the quick uncoupling thereof by the simple pressureof the finger upon the locking device constituting one of the parts ofthe complete coupling.

With these and many other objects in view, which will more readilyappear as the nature of the invention is better understood, the

.same consists in the novel construction, combination, and arrangementof parts, as will be hereinafter more fully described, illustrated, andclaimed.

The essential feature of the invention involved in the novel manner ofconnecting and locking the separate members of the couplingissusceptible tomodification without departing from the spirit or scopeof the invention; but a preferred embodiment of the-latter is shown inthe accompanying drawings, in which V Figure 1 is a perspective view ofa hosecoupling embodying the present invention and shown with the partsin coupled position. Fig. 2 is a longitudinal sectional view of thecoupling with the parts coupled. Fig. 3 is a similar View showing theparts uncoupled. Fig. 4; is a detail sectional view on the line 4 4: ofFig. 2.

forming part of Letters Patent No. 758,956, dated May 3,1904.

erial No. 156,271. (No model.)

In carrying out the invention the coupling proper, as usual, essentiallyconsists of the separate pipe members 1 i and 2, which are connected tothe separate sections of the hose in any approved manner and aredesigned to To insure a perfectly water-tight joint between the separatemembers of the coupling when coupled, it is preferable to provide thepipe member 1 at one end thereof with a flared packed mouth 3, adaptedto receive the tapered joint-nose 1 at one end of'the pipe member 2,said tapering elements 3 and 4 having 'a tight registering fit when thepipe members 1 and 2 are alined, and thereby providing a well-packedtaper joint between the separate members of the coupling to obviateleaking when the same are fitted together.

To facilitate the coupling and uncoupling of the members 1 and 2, aseparable hinge connection is provided between the adjacent ends of thetwo members at one side thereof. This separable hinge connection isdesignated in its entirety by the numeral 5 and essentially consists ofan open bearing-hook 6, projected integrally from one side of the pipemember 1 contiguous to one end thereof, and the open hinge-loop 7laterally offset from the pipe member 2 and projected at an angletherefrom, so as to loosely'and detachably interlock with the book 6.This connection permits the two pipe members to be swung toward and fromeach other in the coupling and uncoupling operation, while at the sametime admitting of the ready separation of these two members when thecoupling is opened up.

To provide for fastening or looking the pipe members when coupled, thereis employed a manually-controlled fastening device, including in itsgeneral organization a swinging latch-bar 8, carried by the pipe member2 and cooperating with the coupling-hook 9 and also with the lockingdevice 10, carried by the pipe member 1. The swinging latch or latchbar8 is provided with a bifurcated end 11, pivotally mounted on the roundedholding- 1 lug 12,projected from the side of the pipe membe coupled anduncoupled in the use of the.

her 2, diametrically opposite the hinge-loop 7, and said bifurcated end11 constitutes a catch-opening adapted to take over and receive thecoupling-hook 9, which is integrally projected from the side of the pipemember 1 opposite the bearing-hook 6 and projects in a direction awayfrom the adjacent end of the pipe member 1, so as to be properly engagedby the opening 11 of the latch and to register over and cooperate withthe holding-lug 12, which passes into the hook 9 when the two membersare united.

The swinging latch 8 when thrown over the hook 9 is designed to becarried into the keeper-seat 13, provided upon one side of the pipemember 1 between the oifstanding seatflanges 1 1, and adjacent to thefree swinging edge thereof the latch-bar has offset from the under sidethereof a catch-plate 15, whose.

edge is adapted to be engaged by the shouldered fastening-hook 16 of thetransverselyarranged locking device 10.

The locking device 10 is in the form of a sliding bolt, mounted insuitable guides or openings provided in the flanges 14: and arrangedtransversely of the seat 13. The said bolt 10 is provided at one endwith a fingerbutton 17 and has coiled thereon an adjustingspring 18,which normally holds the bolt in position for the beveled and shoulderedfastening-hook 16 to be engaged by the latch-plate 15 when the latch-baris pressed down within its seat 13.

Between the locking device and the coupling-hook 9 there is arranged inthe seat 13 an opening-spring 19, which normally exerts its tension in adirection for throwing the latch-bar upwardly to an uncoupling positionwhen disengaged from the locking device or bolt 10 by an inward pressureupon the locking device or bolt.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described hose-coupling will be readilyapparent without further description, and it will also be understoodthat changes in the form, proportion, and minor details of constructionmay be resorted to without departing from the spirit of the invention orsacri-- ficing any of the advantages thereof.

Having thus described the invention, what is claimed, and desired to besecured by Letters Patent, is

1. A hose-coupling comprising separate pipe members having a separablehinge connection at one side, one of said pipe members being providedwith a coupling-hook and a locking device, and a latch pivotally carriedby the other pipe member and engaged by the locking device, the pivotalsupport of the latch being shaped and arranged for engagement within thebight of said hook, substantially as set forth.

2. A hose-coupling comprising separate members having a separable hingeconnection at one side, one of said pipe members being provided with anopen coupling-hook, and a spring-actuated linger-controlled lockingdevice, and a latch-bar pivotally carried by the other pipe member andengaged by the locking device, said bar having an opening receiving theopen coupling-hook whereby the pivotal support of the bar becomesengaged within the bight of the hook.

3. A hose-coupling comprising separate pipe members, one of which isprovided at one side with an open bearing-hook and at its opposite sidewith an oflstanding couplinghook and a keeper-seat, and the other ofsaid pipe members being provided at one side with an open hinge-loop forengagement with said bearing-hook and at the opposite side with aholding-lug adapted to register in the bight of the coupling-hook of theother pipe member, a spring-actuated finger-controlled locking-boltarranged transversely of the keeperseat of one pipe member and providedwith a beveled-shouldered fastening-hook, a swinging latch-bar pivotallymounted upon the holding-lug of one of the pipe members and providedwith a catch-opening for engagement with the coupling-hook and also witha catchplate for engagement with the firstening-hook of thelocking-bolt, and an opening-springarranged in said keeper-seat beneaththe latchbar.

In testimony whereof I aflix my signature in presence of two witnesses.
